Scenarios
Will This Fix My Problem?
Honest answer: here's exactly what this service fixes — and what it doesn't.
Fixes:
- ✓All keys lost on an ML, SLK, SL, W140 or G-Wagen
- ✓Dealer quotes hundreds — or says the key is no longer available
- ✓Bought a classic Mercedes that came with one worn key or none
- ✓Key turns but the immobilizer refuses to authorize a start
- ✓Replaced the AAM or DAS module and nothing starts the car
Won't fix:
- ✗Want remote lock/unlock buttons? The classic remote key service is $375 — same parts shipped
- ✗Module is dead, no-start with a KNOWN-good key? That is the $299 AAM/DAS repair service
- ✗2000s+ EIS/FBS3 cars (chrome SmartKey fob) — see our Mercedes EIS key programming service
- ✗Mechanical ignition or door lock cylinder failures
The era Mercedes forgot
These cars sit in a gap: too old for the dealer's key systems to support gracefully, too new to run without an immobilizer. The fix is going to the module itself — the AAM behind the ML's dash, the DAS/SKREEM unit on the classics — reading its memory on the bench, and generating a key the module already trusts. No dealer authorization involved, because nothing is being looked up: your own module is the source of truth.
Shipping Instructions
These details are also emailed to you the moment your payment clears.
Ship the immobilizer module — the AAM on a W163 ML, the DAS/SKREEM unit on the classic cars (text your VIN FIRST and we tell you exactly which box and where it lives). For all-keys-lost also ship the driver's door lock so we can decode and cut the blade; if you still have a working key, ship that instead and skip the lock. Ship to PO Box 120241, Arlington TX 76012 (USPS) or 1009 Oakwood Ln # 120241, Arlington TX 76012 (UPS/FedEx). Return shipping is selected and paid at checkout — Standard $24.95, UPS 2-Day $54.95, or UPS overnight $94.95.
What to include in your box
- The AAM (W163 ML) or DAS/SKREEM immobilizer module (classics) — we confirm by VIN before you ship
- All keys lost: the driver's door lock (we decode it to cut the new blade)
- Any existing keys, working or not
- VIN + year, and a printed order confirmation
- Your name, return address, and phone number
